LASTIN'G-MAGHINE.

To all whom it may concern:

Be it known that I, ERAsrUs E. WINKLEY, a citizen of the United States,residing at Lynn,'in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Lasting-Machines;and I do hereby'declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to lasting machines and more particularly to thattype of lasting machine known as the hand method lasting machine.

lVhen an upper is pulled over, it is ordinarily secured at the center ofthe tip of the toe and at each side of the forepart about at the ends ofthe tip line. When so secured, the fullness of the upper between thepoints where the fasteners are inserted bulges or bellies out and inlasting a shoe this portion of the upper is ordinarily taken care of byplaiting it over the insole. When the shoe is lasted by hand, or in whatis known as the bed or wiper type of lasting machine, this plaiting ofthe fullness of the upper at the toe is accomplished by wringing theupper with a pair of hand lasting pincers. W ringing, consists inseizing the margin of the upper with the pincers in the usual way andwhile pulling, rotating the pincer jaws to the right or left by a twistof the wrist, this operation being repeated until all the fullness istaken care of. In wringing the upper a turning movement is imparted tothe pincer jaws about an axis extending obliquely to the horizontal, orplane of the shoe bottom, and in the general direction of the pullingmovement. It has been found in practice that a rotary or turningmovement of the pincers about such an axis lays the margin of the uppersnugly to the insole and produces the most efl'ectual plaiting.

One object of the particular machine construction, herein described andillustrated, is to provide mechanical means for laying the fulledportion of the upper to the last as effectively as it can be done byhand.

In accordance with this object, one feature of the machine consists inthe provision, in a machine of the general type specified which alreadyin the mechanical operation of its pincers closely follows the updrawand overdraw movements used in hand lasting,

Specification of Letters Patent.

Patented Feb. 20, 1912. Serial No. 523,770.

of mechanical means for imparting to the pincers, in addition, a turningmovement for plaiting the fulled upper at the toe, similar in its actionon the upper and in its effect to wringing by hand. In the preferredembodiment of this means, the pincer aws are mounted with their grippingfaces at an oblique angle to the horizontal and means is provided forrotating said jaws about an axis in the plane of said gripping faces orin a plane substantially parallel thereto. The turning movement thustakes place about an axis extending in the general direction of theoverdraw movement as in hand lasting. The plaiting movement thusmechanically imparted to the upper is similar in all respects to theplaiting movement obtained by hand manipulation of the pincers.

The feature of the machine described in the preceding paragraph doesnot, however, form a part of the present invention and it is not claimedherein, the description as found in this application being merely forthe purpose of providing a complete disclosure of the machine to whichthe present invention is preferably applied.

One object of the present invention is to provide pincer jaw closing andopening mechanism which, while operating to seize the stock in apositive and unyielding grip, nevertheless permits a free rotation ofthe pincers in plaiting the upper at the toe. In accordance with thisobject, one feature of the invention comprises a pair of pincer jawswhich are pivoted together and are further connected, by means of aninverted toggle, at a point between the jaw pivot and jaw ends. Power isapplied to the toggle by an actuator moving substantially parallel tothe axis about which the pincers rotate, and also moving with thepincers in their rotation. As the toggle is opened and closed, it respectively opens and closes the pincer jaws, an actuation of the jawsbeing permitted whatever the position of the pincers.

In lasting some portions of the upper, for example at the ball of theshoe, it is frequently desirable to impart a turning or rotary movementto the pincers during their straight updraw and overdraw movementswithout imparting any side reach or lateral movement. This cannot beaccomplished with the type of hand method lasting machines with whichthe inventor is familiar. Another object of the present invention,

therefore, is to provide a construction wherein the turning movement ofthe pincers is controlled independently of their lateral movement.

In accordance with this object, a further feature of the inventioncomprises separate trains of mechanisms for imparting lateral andturning movements to the pincers with suitable provision for throwingthese trains of mechanisms into operation independently. Preferably, acommon actuator is employed for operating the trains of mechanismscontrolling both the turning and lateral movementsand the amplitude ofthese movements may be varied independently by separate manuallycontrollable means. Provision is also made for operating these trains ofmechanisms simultaneously.

The features of the invention last described are not limited to use in alasting machine of the type illustrated wherein the pincers are arrangedto rotate about an axis substantially in the line of the overdrawmovement, as they may readily be applied to other types of lastingmachine using differently constructed and arranged pincers.

These and other features of the invention, including certain details ofconstruction and combinations of parts, will be further explained in thefollowing description and then particularly pointed out in the appendedclaims.

The various features of the invention will best be understood from adescription of the preferred embodiment thereof illustrated in theaccompanying drawings, in which the invention has been shown forpurposes of description as applied to the lasting machine exemplified byUnited States patents to Ladd & McFeely, No. 584,74A, and Ladd, NO.597,321.

In the drawings, Figure 1 is a side elevation of a hand method lastingmachine of the type above specified with the improvements contemplatedby the present invention applied thereto. A portion of the forward endof the old mechanism has been broken away to better show the newfeatures of the machine and a part of the new features are shown invertical section; Fig. 2 is a front elevation of the improvements whichhave been made upon the old type of hand method lasting machine; Fig. 3is a detail, in side elevation, of the jaw closing mechanism, showingthe jaws open; Fig. dis an elevation of the parts shown in Fig. 3looking in the direction of the arrow a; Fig. 5 is a section on the line5-5, Fig. 2; Fig. 6 is a section on the line 6 6, Fig. 3, with thepincer jaws rotated 90; Fig. 7 is an elevation, in detail, of aconnection between the pincer controlling rods, to be referred to; andFig. 8 is a detail in section taken on the line 88 of Fig. 2.

In the illustrated embodiment of the invention, 2 (Fig. 1) is a bracketsimilar in its function to the bracket shown in the Ladd & McFeelypatent, hereinbefore re ferred to, as supporting the pincers which, bythe mechanisms described in the patent, have imparted to them themovements necessary to place an upper in overworked position on a last,namely, the pulling or updraw movement, the outward or overdrawmovement, and the sidewise or lateral movement, used with a rotarymovement for plaiting the upper over the toe of the last. In the presentinvention instead of mounting the pincer bar directly in this bracket asin the patent, a sleeve at, depending from the pincer lifting lever 5and passing through the bracket, supports an auxiliary bracket 6 (Figs.1 and 3), which in turn is provided with a carrier 8 for the pincers.The carrier 8 is constructed so that the pincers may be mounted thereinat an oblique angle to the horizontal, the direction being upward andoutward from the plane of the front of the machine and preferably in thegeneral direction of the pull in overdrawing the upper. The pincer bar10 is rotatably journaled within the carrier 8 being held fromdisplacement by an enlargement 9 on its lower end and a sleeve 11 pinnedto its upper end (Fig.

The pincer jaws carried by the pincer bar 10 may be constructed in avariety of ways but, as herein shown, the lower jaw 12 is convenientlyformed integral with the bar 10 and the upper aw 1a is pivotally mounted upon the pincer bar (see Fig. (3). The lower jaw 12 has pivotedthereto, by their lower ends, a pair of links 16 which extend upwardlyat each side of the jaw and which overlap a second pair of links 18similarly mounted upon the upper aw. The free ends of these links arepivotally connected by means of a pin 20 which extends across the pincerjaws and through all four links (Figs. 3 and 4t). The rela tiveproportions of the links 16 and 18 are such that when the jaws areclosed the links are in alinement with each other (see Fig. 1). lVhenthe jaws are open, however, the links are at an angle to each other (seeFig. 3). The two pairs of links thus form two pairs of inverted toggleswhich are utilized to open and close the pincer jaws. In order toactuate the toggles each of the links 16 has pivoted thereto arearwardly and upwardly extending link 22, which are also pivotallyconnected beneath plates 24 to the squared lower end of a spool-shapedsleeve 26 which is slidably mounted upon the lower enlarged end 9 of thepincer bar. By sliding this sleeve on the pincer bar it acts through thelinks 22 and serves to actuate the inverted toggles. In order to operatethe toggle actuator 26,

the plunger 28, which corresponds to the rod, or plunger, for closingthe movable gripper jaw shown in the Letters Patent hereinbeforereferred to, is utilized. In the present construction the plunger 28 isprovided with a diametrically arranged pin 30 which projects from eachside and through slots 32 formed in the plunger supporting sleeve 4. Tothe ends of the pin 30 are connected the-upper ends of links 34, thelower ends of which are in turn con nected to bell crank levers 36mounted upon a pivot pin 38 fixed to the lower end of the sleeve 4. Thebell cranks 36 are provided with rolls 40 which engage between thecollars of the spool-shaped sleeve 26 (see Fig. 2).

In the operation of the machine, which is in all essentials similar tothe operation described in the Ladd & McFeely patent hereinbeforereferred to, the plunger 28 is moved downward through the sleeve 4 toclose the pincer aws. This operation causes the bell crank levers 36 toswing about their pivot 38 carrying with them the sliding actuator 26which acts upon the links 16 of the inverted toggles connecting thepincer jaws moving these links downward about their pivot upon thepincer jaw 12, and causing the jaws to close, as shown in Fig. 1. Itwill be noted that, as illustrated, the toggles are mounted upon thejaws at a point intermediate the pivotal jaw connection to the pincerbar and their grip ping faces. This, in addition to providing for anextremely simple method of actuation for the toggles, is alsoadvantageous for another reason in connection with the rotation of thepincer jaws to be presently referred to. Obviously a single toggle couldbe employed but a pair is used to insure an even pressure, over thewhole surface of the gripping faces, when the stock is seized.

A side reach or lateral movement is imparted to the lasting pincers by atrain of mechanism which may be briefly described as follows: A suitablepath cam, in a cam disk 42 (Figs. 1 and 2) mounted on the driving shaft43, engages and oscillates a cam lever 44 fulcrumed on the machine frameand having at its free end a toothed segment 45 engaging a pinion 46upon a hollow rock shaft 47 suitably journaled in the frame at the righthand side of the machine. At the forward end of the rock shaft 47 thereis mounted a driving shoe 48 which is oscillated as the shaft is rocked,thereby imparting motion to a sliding block 49 carried by the shoe andconnected by a link 50 to the bracket 2 through which the pincers pass.The pivotal point of the pincers in their lateral movement is at theball joint 51 (Fig. 1) at the forward end of the updraw lever 5. Themechanism just described may be, and preferably is,

similar to the mechanism for performing the same function shown anddescribed in the Letters Patent hereinbefore referred to.

The amplitude of the lateral movement imparted to the pincers is variedby shifting the position of the block 49 in the oscillating shoe 48.This is done by sliding the block 49 within the shoe 48 by alongitudinal movement of the sleeve 52 (Fig. 1) on the hollow shaft 47.This movement will cause a rocking ofthe solid shaft 53 located withinthe hollow shaft 47 and a consequent shifting of the block in its shoethrough the connections, illustrated and described in the Letters Patenthereinbefore referred to. Movement is imparted to the sleeve 52 by meansof a bell-crank 54 mounted upon a horizontal pivot on the machine frameand engaging the sleeve with its vertical arm. A rod 55 leading to aknee lever (not shown), similar to that shown in the United Statespatent to Stiggins No. 931,809,'depends from the horizontal arm of thebellcrank lever. On moving the knee lever to the left or right of itscentral position, the rod 55 is moved in a direction to throw the block49, respectively, above or below the center of the hollow rock shaft 47.The amount of movement imparted to the knee lever determines the amountof movement given to the block 49 and in turn the amount of lateralmovement imparted to the pincers by the oscillation of the shoe 48.

The turning movement of the pincers is governed by a controlling devicesimilar to that described for the lateral movement and is operated fromthe same actuating cam. The cam lever 44 is provided with a T-slottedsegment 56 on its rear side, to be referred to again. The lower end ofan adjustable link 58 is adjustably secured'in this segment by means ofa headed bolt 53 (Fig. 8) arranged with its head in the T-slot and itsshank passed through an eye on the lower end of the link. The bolt isheld in place by being threaded into a nut 55 which is constructed inany convenient and well known manner to provide for clamping andunclamping the bolt head to the segment. The link 58 is pivoted at itsupper end to a crank 59 on the rear end of a short rock shaft 60journaled at the upper end of a bracket 62 rising from the frame on theright hand side of the machine. The forward end of the rock shaft 60 hassecured thereto a driving shoe 64 similar to the driving shoe 48 andsimilarly provided with a sliding block 66. This block has secured toit, by means of a cap plate 67, one end of a link which extends acrossthe front of the machine and is connected at its other end to the upperend of a lever 71 pivoted centrally in a support 72 at the upper righthand side of the casting forming the pincer bracket 2. The

lower end of the lever 71 is connected by a.

link 73 to a rack 74, sliding in a transverse guideway 75 in the frontside of the casting forming the bracket 2, and engaging a pinion 76pinned to a vertically arranged shaft 78 mounted for both rotary andvertical sliding movement in journals 7 9 and 80 also at the front sideof the bracket 2 (see Fig. l). The shaft 7 8 has pinned to it, at itslower end, a sleeve 81 and this sleeve is connected to the sleeve 11, onthe upper end of the pincer rod 10, by means of a universal joint 82.

\Vith the construction just described, assuming that the block 66 is ina position in its driving shoe 64L either above or below the center ofthe rock shaft 60, as the shoe is oscillated by the movement of the camlever 14: the lever 71 will in turn be oscillated and the rack 74 willbe reciprocated within its guideway, thus turning the pinion 76 andimparting a rotary movement to the pincer bar 10. In practice, thepincer aws are rotated by means of the rack T t, first throughapproximately 45, to place the pincers in proper position to seize themargin of the upper at one side of the center of the toe, and then backthrough approximately 135 so that at the end of the turning movement thefaces of the pincer jaws are in a plane at approximately right angles totheir position as shown in Figs. 1 and This final, or plaiting, positionof the pincers is shown in section in Fig. 6. Such a turning movementhas been found to lay the fulled upper snugly to the insole. Theamplitude of this movement to suit varying conditions may be controlledby varying the position of the block 66 in its shoe Get. This may bedone by varying vertical movements of a rod 8st, at the right of themachine, which is pivotally connected at 85 to a lever 86 mounted uponan auxiliary bracket 87. The lever 86 is in turn connected by a link 88to the block 66 through a bail 68. The end of the lever 86 which isconnected to the link 88 is provided with a roll which travels in a stationary curved guideway 89 conveniently mounted on the bracket 62. Theother end of the lever 88 is connected to the auxiliary bracket 87 bymeans of a short link 90. The curved guideway, as will be readilyunderstood by those skilled in the art, acts as a compensator, so thatby an equal amount of movement in either direction of the rod 84 theblock 66 shall be placed in symmetrical locations above and below theaxis of the rock shaft 60 to insure an equal throw to the rack Te ineither direction. The link 90 permits the lever 86 to follow themovement of the lower end of the link 88 in the curved guideway 89.Vertical movements are imparted to the rod 84, to shift the position ofthe block 66 in its driving shoe, by means of a conveniently locatedhand lever 100 Fig. 2). This lever 100 is removably pivoted at 63 on thebracket 62 and is provided with a slot 101 (dotted lines) through whichis passed a headed pin 102 removably threaded into the rod 8 1. Thisform of connection, permitting loose play between the parts, is providedto take care of the angular movement of the lever 100. The lever movesbetween pins 103, on a smooth segment 10 1 depending in a convenientlocation from the auxiliary bracket 87, and is provided with a handle105. The lever is maintained in varying vertical positions by means ofthe usual friction washer at the pivot 63. The lever just described maybe, and preferably is the same as the lever e illustrated and describedin the patent to French & Meyer No. 563,471, July 7, 1896, (see Figs. 1and 2) which performs a similar function in an outsole sewing machine.It is, of course, desirable that the hand of the operative be removedfrom the work for the shortest space of time possible. The constructionand arrangement described by which the lever 100 is held in any positionof adjustment permits the lever to be moved from one position to anotherby means of a sharp blow, merely, and thus a minimum amount of time isconsumed in changing the position of the block 66 in its shoe 64-. Thepins 103 perform the same function as the pins 011 the plate 7 of thePatent No. 568,471, they be ing so located that when the lever engageseither, under the blow given it by the operative, the desired amount ofturning movement, to the right or left, is imparted to the pincers.

It will be, of course, understood that when the block 49 is in alinementwith the axis of the shaft 47 and when the block 66 is in alinement withthe axis of the shaft 60, although a continuous oscillatory movement isimparted to the cam lever 44 by its cam, and therefore to the shoes 48and 6%, no movement whatever is imparted to either of the links 50 or70. There will, therefore, under these conditions be no lateral orturning movements imparted to the pincers. If it is desired to impart aturning movement alone to the pincers without any lateral movement, aswhen lasting the ball at times, the hand lever 100 connected to the rod84: is moved in a direction to lift said rod either up or down therebyshifting the block 66 respectively above or below the axis of the rockshaft 60 independently of any movement of the block as. This position ofthe block 66 will cause the devices, for imparting a turning movement tothe pincers to the right or left, to be thrown into operation. If it isdesirable to impart both lateral and turning movements to the pincers,for instance, when lasting the toe, in addition to moving the hand lever100 connected to the rod Set the knee lever connected to the rod 55 isalso moved. A movement of the knee lever shifts the block 49 in its shoe48 and causes the devices, for swinging the pincer carrying bracket 2laterally about the ball and socket oint 51 in the updraw lever 5 as acenter, to be thrown into operation. The hand and knee levers are, ofcourse, preferably operated simultaneously when, with this construction,both lateral and turning movements are to be imparted to the pincers.

Some manufacturers deem it unnecessary to make use of the turningmovement of the pincers without the lateral movement and, therefore, thehand lever 100 for operating the rod 84 may be omitted and the machineprovided with a connection between the rods 84 and 55, such as is shownin Fig. 7. This connection comprises a split sleeve 92 clamped to therod 55 and provided with a projection 93 having a universal jointconnection 94 with the lower forked end 84* of the rod 84. \Vith such aconstruction if the knee lever is moved in a direction to raise or lowerthe rod 55, the rod 84 is also raised and lowered with it and thedevices for imparting both lateral and turning movements to the pincersare simultaneously thrown into operation. When a connection between therods 55 and S4 is used, the connection between the rod 84 and the link86 should be in the form of a universal joint as the movement of thebell-crank lever 54, to which the upper end of the rod 55 is connected,swings this rod slightly forward or back, which movement imparts aslight movement in the same direction to the rod 84.

Before the machine is set in operation, adjustments are made in theusual way to determine the desired initial or starting position of thepincers and with the machine of the present invention a furtheradjustment is made of the lower end of the link 58 in its segment groove56 on the cam lever 44. This adjustment determines the greatest throwthat can be imparted from the cam to the driving shoe 64. The amount ofthis throw is determined by the fullness of the upper on the class ofshoes to be operated upon as, obviously, a scant upper will not permitthe pincers to turn through. as great an angle as will a full upper. Bymeans of this adjustment a proper proportion between the lateral andturning movements of the pincers for all kinds of uppers is provided.

In its operation the machine is substantially similar to the machinedescribed in the Letters Patent hereinbefore referred to. An updrawmovement is imparted to the pincers by means of the lever 5 which isactuated by a cam in the cam disk 96 (Fig. 1). An overdraw movement isimparted to the pincers by means of the longitudinally movablerock-shaft 97 actuated by the combined action of a cam 98 on the rearface of the cam disk 42 and a spring 99 (Fig. 1).

The actuation of the pincers for lateral and turning movements hasalready been described. After the pincers have been closed upon thestock in the manner described, the upward movement of the updraw lever 5causes the sleeve 4 to rise through the bracket 2 carrying with it thepincer supporting bracket 6. The shaft 78, on which the pinion 76 ismounted, slides vertically within its guides 79 and 80 in the bracket 2,moving also, vertically relatively to its actuating rack 74. Thevertical movement of the pinion 76 is, however, never sufficient tocause it to become disengaged from its rack. In the overdraw movementimparted by movement of the shaft 97 the bracket 2, with all the partswhich it supports, is moved forward about the ball and socket joint 51as a center. The ball and socket joints at the ends of the connectinglinks 50 and permit the bracket 2 to move relatively to the pinceractuating shoes 48 and 64 which are mounted upon the frame of themachine.

As heretofore described, the toggle closing mechanism for the pincerjaws is mounted upon the jaws themselves, thus providing for a mountingof the toggle actuator on the pincer bar. This construction permits thetoggle actuator to be operated by means mounted independently of thepincers, while still permitting a free rotation of the pincer aws.

lVhile it is preferred to employ the specific construction andarrangement of the parts shown and described, since this constructionand arrangement is the simplest and most efficient embodiment of theinvention which has yet been devised, it will be understood that thisconstruction and arrangement is not essential except so far as it isspecified in the claims, and may be varied or modified without departingfrom the broader features of the invention.
